What I mean is that if Nintendo decides to release a Wii firmware that renders current modchips (including D2CKey) useless, then chips such as D2pro9v2/v3 and the Wasabi2/3 have a means to update their modchip for continued use, whereas D2CKey does not have that ability. This is all hypathetical and like I said, the D2CKey is going strong without needing any updates thus far, but who know about what will happen, its all upto howmuch risk you are willing to take.
